Hi Noel,

Thank you for the clarification provided.

Previously, the job took ~15min for ALTER ADD Column. But after the below 
changes in JDBC URL, I see the ALTER job got completed in 10mins.

CACHE_SIZE=2097152;LOG=0;LOCK_MODE=0;UNDO_LOG=0

I just need clarification reg ALTER Statement in h2 Database. Is that ALTER 
ADD Column will insert / write *"null"* into all the records after adding 
the new column. So only it is taking long time to complete the task. 

*Regards*,
Prasad
